It will happen. If there's one thing we can count on from these confederations, is their love for the $$, and a Pan-American COPA America will bring in that mulah, especially with the TV rights that would come with that.
Do you mean a great summer for our national teams? Or a great summer for viewing? Because I'd say in terms of viewing, just about every summer is pretty great for us already.
Year 0 - World Cup
Year 1 - Gold Cup & COPA
Year 2 - Euro Cup & Olympics
Year 3 - Confederations Cup & Gold Cup
Year 4 - World Cup
If you mean a great summer for our national teams to play in, I agree. It'll be great to have tougher opposition to our team and play in games that actually matter.
I meant viewing (but it would certainly be great for our national team to play in regularly as well). I don't consider the Gold Cup a very high-level tournament. I mean, I still watch it, since the US is in it. If they weren't though, I probably wouldn't bother. And I don't think the Copa America even airs up here. The Confed Cup is a decent tournament, but it's smaller and shorter than all the others.
A summer of the Euros plus an Americas cup, means we'd get to see (nearly) all of the world's best players and nations compete on an international level every 2 years instead of 4.
